摘要： A walk power mower has a mower deck that encloses a pair of rotary cutting blades with the grass clippings from the blades being discharged through a rearwardly extending grass discharge tunnel in a rear bagging mode of operation. The blades are powered by a timed drive system that is carried by a horizontal apron that is part of a cast aluminum engine mount. The engine mount and the apron are bolted to a stamped steel deck shell that forms the cutting chamber in which the blades rotate. The mower has a side discharge mode in which a side discharge chute is releasably mounted over a side discharge opening. The chute carries a flow cutoff baffle having an inwardly protruding inner end that sticks through the side discharge opening to intercept and direct the clippings out through the side discharge opening and through the chute in the side discharge mode.

摘要： A handle having an adjustable shaft wherein the overall length of the shaft and/or the angular relationship of portions of the shaft can be varied by a user of an associated tool. In one embodiment, the handle includes a first tube, a second tube connected to a working unit of a portable tool, and wherein a portion of the second tube is telescopically received into the first tube. A coupling is provided to receive a portion of the first tube and the second tube. The coupling has a pin stop which engages a pin connected to one of the tubes and defines a limit of a range of relative rotational motion between the first tube and the second tube. In one embodiment, the upper tubular portion of the handle and a control grip are capable of being rotated relative to a working unit.

摘要： A walk behind lawn mower has an exit tunnel that is opened and closed by a pivotal mulch door to convert the mower between collecting and mulching modes of operation. An operating handle fixed to the mulch door includes a vertically reciprocal push button for releasing locking tabs that engage detents for holding the mulch door in the open and closed positions thereof. The bottom wall of the exit tunnel has a steeply inclined rear ramp section that is angled upwardly relative to the horizontal at least approximately 45°. The rear discharge opening of the exit tunnel occupies approximately an upper quarter of the area of the rear face of the cutting deck. Grass clippings flow into the upper portion of a grass collector through this high, steeply angled exit tunnel to promote even and full filling of the grass collector in the collecting mode.

摘要： A filament trimmer includes a rotatable trimmer head having an outwardly extending filament. The trimmer has an upper handle that the operator can grip to operate the trimmer in either a trim mode or an edge mode. In the trim mode, the filament extending outwardly from the trimmer head is positioned in a generally horizontal cutting plane, while in the edge mode the trimmer is reoriented such that the filament is positioned in a generally vertical cutting plane. The upper handle of the trimmer includes dual triggers for selectively starting and stopping rotation of the trimmer head. One trigger is actuated when the trimmer is operated in the trim mode and the other trigger is actuated when the trimmer is operated in the edge mode.

摘要： A lawn mower includes a housing having a cutting chamber defined by a top wall and a circumferential sidewall. A side discharge opening is provided on the sidewall. A side discharge chute selectively opens and closes the discharge opening. The discharge chute has a side door pivoted to the sidewall about a vertical pivot axis and a top deflector pivoted to the side door about a substantially horizontal pivot axis. When the discharge chute is in an open position to open the discharge opening to the flow of grass clippings, the top deflector pivots downwardly on the side door into an inclined position to intercept the grass clippings and direct them downwardly towards the ground.
